Full job description

Systems Administrator (Junior) — Dublin

Multisys designs, builds and supports enterprise IP CCTV and the networks, control rooms, head ends and Video Walls — for critical infrastructure across national transport, government and a small number of large private-sector clients. We are small, agile, flat, and we keep our people. Most of what we support, we built.

The role

A Dublin-based role supporting our largest accounts. It's part helpdesk, part hands-on systems maintenance — but not the helpdesk you're picturing. We support a handful of clients, not the public, and the systems are enterprise-grade: thousands of cameras, hundreds of Windows servers and clients, switches, video walls and the networks tying them together. Call volume is manageable; the variety is wide. There is always something to fix, improve or harden. We know all of our customers well.

First and foremost this is Windows systems administration — the servers, the clients, and the applications running on them, kept patched, secure and current. Around that sits basic access-layer networking and the connected IP edge devices that depend on it: cameras, access control, sensors and controllers. You'll resolve faults across a national footprint — sometimes from a desk, sometimes on site. The sites are often of national significance and mission critical. You'll work directly with senior engineers and get real ownership fast.

What you'll work with

Windows server and client estates, and the applications that run on them — physical and virtual. This is the core of the role.
Basic access-layer networking — under the supervision of a world-class Cisco expert instructor
Connected IP edge devices — cameras, access control, sensors and controllers
Enterprise VMS / CCTV platforms (Genetec experience a strong plus — we'll train the right person)
Control-room video wall systems
Structured cabling, copper and fibre
Cybersecurity: patching, hardening, secure configuration

We've recently added access control to our services — hands-on experience there is a real plus. Otherwise we value attitude and aptitude over a list of certs: missing some of the above but a fast learner is fine.

Who we want

This is the part that matters most: we are happy to take on someone junior — light on experience, or without formal qualifications — as long as they show us the right attitude. Skills and knowledge we can teach. Attitude we can't.

So: a sharp young engineer with something to prove. Self-starting, structured but lateral, able to finish what they start. We place a lot of weight on focused, even obsessive thinking and a neat, tidy mind — in how you approach a problem and how you keep your work. Someone who'll dig into a broken site at 9pm and not walk away, who can hold their own under pressure and back their own judgement. We care less about your CV than whether you stick with a problem until it's solved. A master's in cyber security counts for nothing if you can't tell us what an IP address is — whatever your background, you'll be expected to prove competence as a person or in technology.

Essential — you need all of these

Currently living in Ireland, or able to relocate immediately
The legal right to work in Ireland
Fluent English
Comfortable making and receiving phone calls — it's a core part of the role
Full driving licence
Able to pass Garda vetting

Full-time, permanent. Dublin base, travel across Ireland (occasional UK).

Bike to work scheme
Company events
Company pension
